To a?! whom it may concern: I

Be it known that I. EIXIR Vt. Siros si ii. -a citizen of the United.States of. America, and a resident of Asbury Park, in the county ofMonmouth and State of New Jersey, have'invented a new and ImprovedSpring Connectiom of which the following is a description,

My invent'on relates to a means to connect the ends of a spring to theside bar of a frame of an automobile or other vehicle. The invention hasin view twisting or dis tortion of the spring due to an axle rising ordropping at one end. I

The general object ofmy invention is to provide a universal connectionfor each end of the spring of a character that will enable the spring'toinstantly conform totho angular position of the axle due to rising orfalling of one wheel of" the axle, rclz: timely .to the opposite end ofthe axle.

I A more specific object of the invention is to provide a universalspring connection that will eliminate or minimize the strains on theconnecting means as 'well'as to provide a connectingmeans involving fewparts of simple form andof the necessary strength.

The nature of my invention and its distinguishing features and"advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part ofthis speci fication, it being understood that the draw-' ings are merelyillustrative of one example of the invention.

Figure 1 is a side elevation of a spring secured to a frame bar by myimproved spring connection Figure 2 is an enlarged detail in section ina plane indicated by the line 2-2, Figure 1;

Figure 3 is a longitudinal vertical section of the spring connection atone end of the spring. I

In the illustrated example the letter A indicates a fragment of the sidebar of a chassis frame.the letter B an axle in cross section; and b theaxle clips.

In carrying out my invention in accordance with the illustratedexample,one end of the spring is supported'on an element usually called agooseneck forming the terminal of the frame bar A. Said element 10 has asocket section 11 whichis thus rigid with. the bar A. The socket iscompleted by a section '12, the sections 11, 153

having earslS secured by bolts 113 to hold said .sections'in rigidrelation. At that side of the socket 11 toward the spring a slot 14 isformed jointly in the sections 11 and 12. The hall 15 for completing theball and socket connection with the spring, and the terminal element 10of bar A; is formed with a shank 16- which passes from the ball outwardly through the slot 14 and provided with means to effect such aconnection with the spring as to permit the ball 15 to acc'on'rmodateitself to all movements of the spring as will appear.

(hi that end of the shank 16 opposite the ball 15 is fork 1'? the undermember 18 of wh ch is shorter than the top member of the, fork and bothmembers are secured to the uppcrfor longest leaf 19 of the spring. Thenext leaf 20 below the topmost leaf 19 is shorter and the third leaf 211s aganr lengthened, beyond the intermediate leaf 20' i and approximatesin length the leaf 19. The numeral 2 indicates the successively shorterleaves at the under side of the spring. which leaves 22 may be providedin any su table through side lugs 26 integral with the longer member offork 17 and receive nuts 27, the

said shanks of shackle 2 1 lying at the sides of spring leaf 19. It willbe observed that the leaf 20 directly beneath the topmost leaf 19terminates adjacent to'the clip 24 and it will be seen that the nextlowermost leaf 21 extends beneath and covers said clip 21 and beneathand covers the bolt 23, the head of which bolt 23 is countersunk in thelower shorter member 18 of fork 17.

The opposite end-of the spring is connected with the frame bar A orother fired support "according to the. position ofthe spring on thevehicle by a ball and socket connection essentially the same asdescribed with respect to the connection of the spring with the element10. In the'illustrated example a known hanger or shackle 28 is provided'on the bar A distant from the element 10 and has integral therewith asocket section 111 therein, corresponding with the g section 11, therebeing a mating socket secs tion 112 corresponding With the socketsection 12, and said sections 111, 112 having flanges 213 secured bybolts 313. The ball 15 is employed in the socket formed by the sections111.. 112 the same as in the socket formed by the sections 11 and 12 andhas the described shank 16 and the fork 17 as well as the fasteningmeans for said fork all as described in connection with the devicespertaining to the ball 15 in the socket sections 11 and 12.

Yith the described arrangement, it will be seen that the axis of theshank 16 and ball 15 is in line with the main leaf oi: the spring andthat the hall and socket connection at both ends are in the same line.The resnlt is that the balls in the sockets are free to conform to an;bending, "Wisting, or other distortion of the sprii 1. If one Wheel ofthe a xle rises or sinks rel-ativel to the other wheel. the spring in ifor example. be given movement which nonld tend to swing; the forkedshank 1.6 and the l ills thereon bodily through an are but this tendencyWill not develop with the arrangement described because any twis -ins;movement of the spring or a movement shout an axis coincident with thearses of the balls 15 will result in a turning: movement about the saidaxes. The consequence that there can he no binding of the balls in theirsockets such as would occur were the spring balls not in line with eachother and the hal s in line with the shank 16 and with the respectiveends of the main spring: leaf. Moreover, the forming of the ball withthe forked shank 16 integral therewith and the described manner offastening said fork to the spring, result in the inaxin'nnn strength.

I would state in conclusion that while the illustrated exampleconstitutes a practical embodiment of my invention; 1 do not limitmyself strictly to the exact details herein illustrated, since,manifestly, the some can be considerably varied without departure fromthe spirit of the invention as defined in the appended claims.

Having thus described my invention. 1 claim:

1. A spring. and means to secure the same. said means comprising;sockets, balls in said sockets and capable of universal inoven'ienttherein, shanks rigid With the balls t posed at the sides toward theends of the spring, forks on the outer ends of the shanks. said forkspresenting one arm longer than the other. shackles securing the ends ofthe main leaf of the sprin to the longer arm of the fork said ends ofsaid leaf extending between the members of the fork and each enddisposed in line with the axis of the adjacent shank and ball, and boltsfastening both the longer and shorter arms of the forks and therespective ends of said spring together.

2. A spring and means to secure the somev said means comprising sockets,balls in said sockets and capable of universal movement the-rein, shanksrigid with said balls and d s posed toward the ends of the spring, for7s rig-id with the outer ends of the shanks, said forks receiving theends of aleaf of the spring, and means fastening said forks to aidspring leaf.
